Large, easy-to-read dial lets you adjust flow, quickly and simply, while pump is running. Can be locked in position to maintain constant flow. Precision stroke adjustment can be operated while in use. Steady State Accuracy ~ + 1% of full capacity over the 10 to 1 turndown ratio.

What our clients say

“We’re tissue sampling our corn and then using an Agri-Inject
G110 to apply about 30 units of 32 percent liquid nitrogen
through the pivot right before tassel. Last year,
we had so much rain, we had trouble keeping
our nitrogen levels up. We did see a response
when we took tissue samples a second time
after the application. In my area, most of
the Extension specialists and seed companies
are saying the most efficient way to get the
maximum effect from your fertilizer is to
do a late season application. We already
have seven pivot irrigation systems, so
this is really the direction we’ve been
trying to go.”

“I’m actually using two different Agri-Inject units. One is an Insectigator that I use to apply a mix of fungicide and insecticide on corn-on-corn, while the other is a 110-gph fertigation system that is used for split applications of nitrogen on corn. Articles I’ve read say that 100 units of nitrogen is all that corn can handle at one time. Of course, there’s no way we could put on the 275 units of nitrogen that we put on during the season in one or two applications. So we’re applying a large part of it through the pivot so the plants get it when they need it most. So far, I’ve been really pleased with the system and the results.” — Joel Armistead, Adairville, Kentucky
